The height of the water in a pool is proportional to the minutes it takes for the pool to fill up. If the height of the water is 2 inches after 5 minutes, what is the constant proportionality/constant of variation in this situation

Answer:

24/35

Step-by-step explanation:

Answer:

201.45 cm²

Step-by-step explanation:

The whole circle has an area of π(9)² cm², or 81π cm². The shaded part represents all of the circle except for the chunk swept out by sector XZ.

Sector XZ sweeps out 75°, which represents 75/360 of the whole circle, or, simplified, 15/72. That means the shaded area must represent the other 57/72. To find the area then, we can just multiply that fraction by 81π:

[tex]81\pi\cdot\frac{57}{72}=9\pi\cdot\frac{57}{8}[/tex]

Using π ≈ 3.14 and crunching the numbers out gives us a result of approximately 201.45 cm².

Answer:

No. He had not made cherry pink paint

Step-by-step explanation:

Rose Pink red : white = 1 : 2

Cherry Pink red : white = 4 : 3

...he adds 80 litres of red paint and 28 litres of white paint.

The question basically want us to check if it follows the ratio.

To have the cherry pink, the ratio must be 4:3 however the ration of paint he mixed is;

80 : 28 which is equivalent to 20 : 7

This means he had not made cherry pink paint

Adding 80 litres of red paint and 28 litres of white paint to the 60 liters of Rose pink paint does not make Cherry pink paint

The ratios are given as:

Rose pink paint-> Red : White = 1 : 2

Cherry pink paint-> Red : White = 4 : 3

When he makes 60 liters of Rose pink paint, the proportion of white and red paints are:

[tex]Red = \frac{1}{1 + 2} \times 60[/tex]

[tex]Red = 20[/tex]

[tex]White = \frac{2}{1 + 2} \times 60[/tex]

[tex]White = 40[/tex]

He then adds 80 liters of red and 28 liters of white paints.

So, the new proportions are:

[tex]Red = 20+80[/tex]

[tex]Red = 100[/tex]

[tex]White = 40+28[/tex]

[tex]White = 68[/tex]

Express as ratio

[tex]Red : White = 100 : 68[/tex]

Simplify to the smallest term

[tex]Red : White = 25 : 17[/tex]

25:17 is not equivalent to 4:3.

Hence, he has not made Cherry pink paint

= 4.1/100 × 30

= 41/1000 × 30

= 123/100

= 1.23%

Answer:

1.23

Step-by-step explanation:

Hey there !!!!!

4.1% of 30

if we solve it :

Y is 4.1% of 30

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 4.1% * 30

Converting percent to decimal:

p = 4.1%/100 = 0.041

Y = 0.041 * 30

Y = 1.23

therefore:

4.1% of 30 = 1.23

Answer:

1. infinite solutions.

2. no solutions.

Step-by-step explanation:

a. 8x + 7 = 8x + 7

The expressions are equal to each other; therefore, the equation has infinite solutions.

b. 10t - 6 = 10t + 6

10t = 10t + 12

0 = 12

These terms do not equal each other. 0 does not equal 12; therefore, this equation has no solutions.

Answer:

∠ HGL = 73°

Step-by-step explanation:

KL is a midsegment of the triangle and is parallel to HG, then

∠ KLJ = ∠ HGL ( corresponding angles ), so

9x - 62 = 5x - 2 ( subtract 5x from both sides )

4x - 62 = - 2 ( add 62 to both sides )

4x = 60 ( divide both sides by 4 )

x = 15

Thus

∠ HGL = 5x - 2 = 5(15) - 2 = 75 - 2 = 73°
